9 Claims. (Cl. 222-165) This invention relates to a receptacle forstoring and handling small parts such as bolts, nuts, washers and thelike, and is particularly concerned with a structure adapted to receivethe parts in their original container such as a box or keg and by asimple manipulation to eject the parts from the container and disposethem in a ready position for use.

In many factory operations, particularly in assembling, where a numberof adjacent workmen are performing the same or similar operations, it ishighly desirable that a regular supply of the various parts involved inthe as-' sembling be maintained in a position convenient to the workers.It is also desirable that the parts be so disposed that a number ofworkers can utilize the same source of supply and that this be done witha minimum of effort and inconvenience to one another.

In a typical factory assembly operation, a group of workers performingthe same step or successive steps which require utilization of the sameparts conventionally will work side by side along a bench or a series ofbenches. If the step or operation is to be performed on the bench withthe workmen facing it, it is conventional to dispose the parts to therear of the workmen on tables or benches adapted for this particularpurpose. It is also customary, in large factories particularly, toprovide employees charged with the duty of maintaining a regular supplyof parts for the assemblers. Usually this is done by simply depositingthe original parts containers on the benches or tables at the rear ofthe workers and replenishing the supply from time to time asreplenishment is indicated.

In accordance with this practice, the assemblers are required to dipmanually into the container and, particularly if the supply of parts islow, this is an awkward and time consuming operation. Emptying thecontainer on the bench or table is messy, space consuming and equallyunsatisfactory. After the supply from the container has been exhausted,there is apt to be a material time lag before the supply is replenished.All of these factors tend to add to the cost of the manufacturingoperation.

The basic concept of the present invention has been to create a partsreceptacle and dispenser into which the person charged with the duty ofmaintaining the supply of parts can insert the original container andthen quickly and readily manipulate the device to an inverted positionto eject the parts from the container into the receptacle to a positionwhere they can be utilized with a maximum of efiiciency by one or aplurality of workmen. When the supply has been fully utilized-the devicecan then be returned to its original upright position by the workmen,and such positioning in a row of like devices constitutes a signal tothe parts supplying employee that more parts are required at thisparticular point. In this way there is a minimum of time lag inreplenishing the supply for the workmen.

In its inverted dispensing position, the receptacle is poised along adownwardly inclined axis and the parts naturally flow by gravity.fromthe inverted container within it, then downwardly into an open chuteat the lower end of the receptacle. The level of the mass of parts inthe chute is controlled by a gate extending across the chute; toaccommodate the How characteristics of various kinds of parts, the gatemay be adjusted to different elevations in the chute. As the parts aredipped out they are replaced by others which flow outwardly from beneaththe gate into the forward portion of the chute, thus keeping the levelconstant until the supply is exhausted.

In the drawings there is illustrated a preferred embodiment of a deviceembodying the principles of the invention.

the device in loading position.

ly at 19, having a hopper or receptacle 11 pivotall} mounted upon it bythe trunnions or pivot pins 12. Thepivot pins are mounted on each of theside walls of the re-- ceptacle in corresponding positions and projectoutward-- ly from the mounting pads 13. The mounting pads are attachedto the side walls by the screws 14 and by weld-- ing as at 15.

The base 10 is generally U-shaped as viewed from the front (Figure 2)and is fabricated from heavy gauge sheet metal. It comprises a bottomplate 16 pierced with holes for optional permanent fastening to a tableand spaced side walls 17 rising vertically from the bottom plate inparallelism with one another. The side edges of the walls convergeupwardly toward one another from the bottom plate in triangle fashionand terminate in a flat upper edge 18 which includes an open slot 20.The pivot pins are rotatably journalled in the slots at opposite sides,permitting the receptacle to be pivoted from the upright loadingposition shown in Figure 4 to the inverted dispensing position shown inFigure 3. The projecting portion of each pivot pin has a groove 21corresponding in width to the thickness of the side walls 17 of the baseto center the receptacle between the side walls.

Positioned on the baseplate 16 at the rear thereof and secured to theside walls 17 by welding or the like is a channel member 22. This memberextends completely across the base and serves as a support for thebottom of the receptacle when the receptacle is in upright loadingposition as in Figure 4.

The width of the receptacle, as viewed in Figure 2, is slightly lessthan the spacing of the side walls 17 of the base such that theclearances, as indicated at 23, are provided between the receptacle andits supporting base. The receptacle is fabricated from sheet metal andis of square, box-like construction having an open face 24 and aninclined dispensing chute 25 at one end.

Described in detail, the receptacle includes a pair of side walls 26, arear wall 27 and an end wall 28. The side walls include right angularmarginal flaps 30 which are secured to the rear wall, preferably bywelding. The end portions of the sidewalls, as viewed in Figure 3, areinclined outwardly from the rear toward the open face to provide theangle of the dispensing chute 25. The rear wall 27 is correspondinglybent to provide the chute bottom or flow plate 31. The forward endportion of bottom 31 is bent upwardly to form a generally verticalretainer lip 32.

When the receptacle is in its inverted dispensing position (Figure 3),the parts flow by gravity from the original parts container, such as thekeg 33, indicated in broken lines, then down the inclined flow plate 31toward the open face of the chute. The flowing parts are restrained bythe lip 32 such that a mass of parts is confined in the chute to bedipped out by the workmen as needed. The parts naturally assume an angleof repose in the chute at a level determined by the gate 34 which may beadjusted vertically in accordance with the nature of the parts.

The gate extends completely across the open face of the receptacle(Figure 2) with its lower edge portion projecting downwardly into thechute toward the flow plate 31. The lower edge thus defines an outletopening 35 leading into the open forward portion of chute 25. The upperportion of the gate, or more precisely, its mounting structure asdescribed later, forms a barrier adjacent the open end of the container25; in other words, the gate structure and adjoining portions of thereceptacle form a hopper area 36 immediately below the open end of thecontainer to receive the parts and to feed them forwardly into the openportion of the chute.

Described in detail with reference to Figure 3, the gate 34 is supportedby a closure plate 37 which is pivotally connected by the screws 38 tothe side walls of the receptacle. As described later in detail, theclosure plate, with the gate mounted upon it, may be swung about theplvot screws outwardly as shown in Figure 4, to allow the container tobe placed in the upright receptacle. In the inverted position of thereceptacle shown in Figure 3, the angular pivoted portion 40 of themounting plate lies in a generally perpendicular plane and the swingingportion 41 resides flush with the open face of the receptacle. It willalso be noted that the pivoted plate portion 40 resides in a planesubstantially at right angles to the chute bottom or How plate 31. Theclosure plate is provided with flanges 42 along its opposite side edgeswhich nest between the side walls 26 of the receptacle. The pivot screws38 pass through the flanges 42 and walls at opposite sides and includenuts 43 at the external surface of the receptacle.

Referring to Figure 3, the gate 34 is mounted upon the angular portion40 of the closure plate at right angles to the chute bottom 31 forvertical adjustment by loosening the wing nuts 44 which are threadedupon the screws 45. The screws project forwardly from the closure plateand have heads 46 welded to the plate. The threaded portions of thescrews project outwardly through slots 47 formed in the gate (Figure 2).Upon loosening the wing nuts, the gate may be raised or lowered bygrasping the handle 48 which is welded to the external surface of thegate. This adjusts the size of the outlet opening 35 as required by thesize of the parts or other factors. For stiffening purposes, the sideedges of the gate are provided with the angular flanges 50.

In its closed position, the closure plate 37 is locked by a pair ofswinging latches 51 which are pivotally mounted as at 52 upon the sidewalls of the receptacle. A standard tension spring (not shown) is placedon the pivot pins 52 between the latches and wall to hold the latches byfriction in any desired position. The swinging end of each latch isprovided with a slot 53 which engages respective latch pins 54 mountedupon the flanges 42 of the closure plate. In order to provide clearancefor the latch pins 54, the side edges of the receptacle walls includegenerally -shaped open slots 55 which are shaped in accordance with thearcuate path described by the pin as the cover plate is swung to itsopen position about pivot screws 38. Each latch 51 is provided with aflange 56 along its upper edge, providing a hand grip for manipulatingthe latch. When in closed position (Figure 1), the engagement of thelatch pins 54 in notches 55 limits the inward position of the closureplate.

The latch structure is in duplicate at opposite sides of the receptacleand the latched closure plate engages the periphery of the keg 33 toconfine it in the receptacle. The rearward portion of the keg is cradledabout three sides Within the side and rear walls of the recepacle. Inits inverted position shown in Figure 3, the lower end of the keg restsagainst the inclined pivoted portion 40 of the closure plate to restrictthe keg against motion along its inclined axis.

When the recepacle is pivoted to its upright position for loading asshown in Figure 4, the end wall 28, which new forms the bottom of thereceptacle, rests upon the transverse channel 22 of the base. Thissupports the receptacle in stabilized condition to receive the keg orother parts container. The dispenser is preferably mounted upon aworktable, as indicated earlier, in order to supply the parts at aconvenient elevation to the workmen. In the upright position, the bottom28 is disposed in a plane slightly elevated above the supporting surfacefor conveniently inserting the container.

Before the parts container is placed in the upright hopper, the latches51 are swung to a disengaged position and the closure plate is swungupwardly about its pivotal axis to the open position shown in Figure 4-.It is latched in this position by either of two retainer arms 61 whichare pivotally mounted at each side of the receptacle. The pivoted end ofeach arm is connected to the receptacle by the pivot screw 62 whichincludes a nut 63 externally of the receptacle. The outer or swingingend of each retainer arm includes a notch 64 which engages the latch pin54 to lock the cover plate in elevated position. In this position acontainer of parts can readily be placed in the receptacle from theside. The pivot screw 62 of the retainer arm is spaced upwardly from thepivot screw 38 of the closure plate, such that the arm and closure plateare angularly related when in latched position, with the load carried intension by the arm. After the container is placed in the receptacle, theretainer arm is released and the closure plate is swung to closedposition, then latched as shown in Figure 1.

In upright position, the receptacle is slightly overbalanced to theleft, as viewed in Figure 4, the location of pivot bearings 12 beingslightly off center to the right for this purpose. The outwardlyprojecting closure plate assembly increases the overbalance. Thereceptable is stabilized in this position by engagement of its bottomagainst the transverse channel 22. After the closure plate is closed andlatched, the receptacle, with the parts container in it, is rotatedabout its trunnion bearings toward the right as indicated by the arrowin Figure 4. The pivot bearings are located somewhat above the center ofgravity of the upright receptacle and, as noted above, off center to theright as viewed in Figure 4. When loaded, the receptacle is poisednearly in balance with its contents forming a partial ballast tending tostabilize it in upright position; therefore, even with a heavy load, thereceptacle can be pivoted towards its inverted position withoutexcessive effort. As the inclination of the axis of the receptacle andcontainer increases, but before reaching the full inverted position, thecontainer will slide downwardly to the position shown in Figure 3;thereafter, the parts within it will flow into the hopper 36 and throughthe opening 35 into the open forward portion of the chute.

It will be noted in Figure 3, that the shifting of the container andparts toward the chute will cause the cen ter of gravity of thereceptacle to shift to some point below the axis of the trunnionbearings. Therefore, when inverted, the receptacle is overbalanced andis stabilized in this position by the engagement of the forward positionof the chute upon the supporting surface as indicated at 65 in brokenlines. It will be understood that, in its inverted position, the majorweight load of the receptacle is carried upon the trunnion bearings,while a minor portion of the load overbalances the receptacle ininverted position. The bottom plate of the base has a substantial widthand firmly stabilizes the receptacle in its inverted dispensingposition.

As the parts are dipped out of the open forward end of the chute, theyare replaced by other parts flowing through the opening 35 as explainedearlier. The angle of inclination of the receptacle and container causesthe parts to flow naturally until the supply is exhausted. At this timethe receptacle is pivoted back to its upright position for replacementof the empty container with a filled one.
